Enso Teleconnection Pattern Changes Over The Southeastern United States Under A Climate Change Scenario In Cmip5 Models, Ji-Hyun Oh, D.W. Shin, Steven D. Cocke, Guillermo A. Baigorria

School of Natural Resources: Faculty Publications

A strong teleconnection exists between the sea surface temperature (SST) over the tropical Pacific and the winter precipitation in the southeastern United States (SE US).This feature is adopted to validate the fidelity of Coupled Model Intercomparison Project Phase 5 (CMIP5) in this study. In addition, the authors examine whether the teleconnection pattern persists in the future under a global warming scenario. Generally, most of the eight selected models show a positive correlation between November SST over Ni˜no 3 region and December–February (DJF) mean daily precipitation anomalies over the SE US, consistent with the observation. However, the models with poor realization …

Modeling The Snow Surface Temperature With A One-Layer Energy Balance Snowmelt Model, J. You, D. G. Tarboton, C. H. Luce

School of Natural Resources: Faculty Publications

Snow surface temperature is a key control on and result of dynamically coupled energy exchanges at the snow surface. The snow surface temperature is the result of the balance between external forcing (incoming radiation) and energy exchanges above the surface that depend on surface temperature (outgoing longwave radiation and turbulent fluxes) and the transport of energy into the snow by conduction and meltwater influx. Because of the strong insulating properties of snow, thermal gradients in snow packs are large and nonlinear, a fact that has led many to advocate multiple layer snowmelt models over single layer models. In an effort …

Speleoclimate Dynamics In Santana Cave (Petar, São Paulo State, Brazil): General Characterization And Implications For Tourist Management, Heros Augusto Santos Lobo, Paulo Cesar Boggiani, José Alexandre De Jesus Perinotto

International Journal of Speleology

Show caves provide tourists with the opportunity to have close contact with natural underground spaces. However, visitation to these places also creates a need for management measures, mainly the definition of tourist carrying capacity. The present work describes the results of climate monitoring and atmospheric profiling performed in Santana Cave (Alto Ribeira State and Tourist Park – PETAR, Brazil) between 2008 and 2011. Based on the results, distinct preliminary zones with different levels of thermal variation were identified, which classify Santana Cave as a warm trap. Two critical points along the tourist route (Cristo and Encontro Halls) were identified where …

Decision Support Tools To Address Climate Change: Climate Model - Land Surface Models, Zea Mays L. (Corn) Phenology And Evapotranspiration-Yield Sensitivity Models For Nebraska, Usa., Jane A. Okalebo

School of Natural Resources: Dissertations, Theses, and Student Research

Nebraska's climate is highly variable and is expected to change in the future with anthropogenic global warming (AGW), resulting in warmer spring and summer temperatures coupled with more erratic rainfall events. This has strong implications for agriculture in the region, yet it is not clear that current modeling and decision-support tools are adequate to address these looming changes and provide planning, mitigation and adaptation strategies. To address climate change and its implications to agriculture in Nebraska, a set of robust decision support tools are very crucial. This study herein are divided into three chapters, with each chapter addressing a specific …

The Effect Of Weather During Rearing On Morphometric Traits Of Juvenile Cliff Swallows, Erin A. Roche, Mary Bomberger Brown, Charles R. Brown

School of Natural Resources: Faculty Publications

Episodes of food deprivation may change how nestling birds allocate energy to the growth of skeletal and feather morphological traits during development. Cliff swallows (Petrochelidon pyrrhonota) are colonial, insectivorous birds that regu­larly experience brief periods of severe weather–induced food deprivation during the nesting season which may affect offspring development. We investigated how annual variation in timing of rearing and weather were associated with length of wing and tail, skeletal traits, and body mass in juvenile cliff swallows reared in southwestern Nebraska during 2001–2006. As predicted under conditions of food deprivation, nestling skeletal and feather measurements were generally smaller …

Translating Aboveground Cosmic-Ray Neutron Intensity To High-Frequency Soil Moisture Profiles At Sub-Kilometer Scale, R. Rosolem, T. Hoar, A. Arellano, J. L. Anderson, W. J. Shuttleworth, X. Zeng, Trenton E. Franz

School of Natural Resources: Faculty Publications

Above-ground cosmic-ray neutron measurements provide an opportunity to infer soil moisture at the subkilometer scale. Initial efforts to assimilate those measurements have shown promise. This study expands such analysis by investigating (1) how the information from aboveground cosmic-ray neutrons can constrain the soil moisture at distinct depths simulated by a land surface model, and (2) how changes in data availability (in terms of retrieval frequency) impact the dynamics of simulated soil moisture profiles. We employ ensemble data assimilation techniques in a “nearly-identical twin” experiment applied at semi-arid shrubland, rainfed agricultural field, and mixed forest biomes in the USA. The performance …

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

Connections Between Student Explanations And Arguments From Evidence About Plant Growth, Jenny Dauer, Jennifer H. Doherty, Allison L. Freed, Charles W. Anderson

School of Natural Resources: Faculty Publications

We investigate how students connect explanations and arguments from evidence about plant growth and metabolism—two key practices described by the Next Generation Science Standards. This study reports analyses of interviews with 22 middle and high school students postinstruction, focusing on how their sense-making strategies led them to interpret—or misinterpret—scientific explanations and arguments from evidence. The principles of conservation of matter and energy can provide a framework for making sense of phenomena, but our results show that some students reasoned about plant growth as an action enabled by water, air, sunlight, and soil rather than a process of matter and energy …

Macroinvertebrate Prey Availability And Food Web Dynamics Of Nonnative Trout In A Colorado River Tributary, Grand Canyon, Daniel P. Whiting, Craig P. Paukert, Brian D. Healy, Jonathan Spurgeon

School of Natural Resources: Faculty Publications

Nonnative fishes have been linked to the decline of native fishes and may affect aquatic food webs through direct and indirect pathways. These concerns have led to efforts to remove nonnative Brown and Rainbow Trout, which are abundant in tributaries of the Colorado River, to enhance native fish communities. We sampled fish, benthic, and drifting macroinvertebrates in November 2010, January 2011, June 2011, and September 2011 to assess resource availability and to evaluate the effects of nonnative Brown and Rainbow Trout in a tributary of the Colorado River in the Grand Canyon. We evaluated trout diets from stomach samples collected …

An Interpretive Plan Guide For Wilderness Park In Lincoln, Nebraska, Rachel J. Ward

Community and Regional Planning Program: Professional Projects

Wilderness Park, located in Lancaster County, Nebraska, is a public park of unique ecological and historical value to the city of Lincoln and to the surrounding region. The natural and historical features of the park present an opportunity to communicate environmental and historical topics that are relevant on local, national, and global levels, as well as inspire a lively sense of pride in the community. The problem is that many topics relevant to Wilderness Park are not currently being interpreted at the park, and that there are relatively few interpretive resources available to park visitors.

The purpose of this project …

Light Pollution Research Through Citizen Science, John Kanemoto

STAR Program Research Presentations

Light pollution (LP) can disrupt and/or degrade the health of all living things, as well as, their environments. The goal of my research at the NOAO was to check the accuracy of the citizen science LP reporting systems entitled: Globe at Night (GaN), Dark Sky Meter (DSM), and Loss of the Night (LoN). On the GaN webpage, the darkness of the night sky (DotNS) is reported by selecting a magnitude chart. Each magnitude chart has a different density/number of stars around a specific constellation. The greater number of stars implies a darker night sky. Within the DSM iPhone application, a …

Climate Change: Threats To Social Welfare And Social Justice Requiring Social Work Intervention, Lauren Caroline Achstatter

21st Century Social Justice

The article looks at climate change though a social development framework, with emphasis on social justice and social welfare. It evaluates how market-based capitalism continues to contribute to the problem while ignoring the warnings from the scientific community. The article goes on to report that despite the devastation of climate change, concerns – mainly financial in nature - continue to hinder progress towards reform. The article then argues that given the evidence, climate change qualifies as a topic of interest for social workers. The article goes on to advocate for social work involvement highlighting some suggested areas for action.

Juvenile Green Sturgeon (Acipenser Medirostris) And White Sturgeon (Acipenser Transmontanus) Behavior Near Water-Diversion Fish Screens: Experiments In A Laboratory Swimming Fume, Jamilynn B. Poletto, Dennis E. Cocherell, Natalie Ho, Joseph J. Cech Jr., A. Peter Klimley, Nann A. Fangue

School of Natural Resources: Faculty Publications

Water diversions that extract fresh water for urban, industrial, and agricultural uses, as well as export to southern California, are prevalent throughout the Sacramento–San Joaquin watershed. Many water diversions are fitted with fish-exclusion screens designed to prevent fish from entrainment (i.e., being drawn in). The impact of fish screens on the behavior of migrating juvenile fishes remains largely unknown, especially for threatened species such as sturgeon. We placed individual juvenile green (Acipenser medirostris) or white (Acipenser transmontanus) sturgeon in a laboratory swimming flume in the presence of standard fish screens (2 mm bar spacing) at two …

Patch-Burn Grazing Effects On Cattle Performance: Research Conducted In A Working Landscape, Stephen L. Winter, Samuel D. Fuhlendorf, Mark Goes

School of Natural Resources: Faculty Publications

• Patch-burn grazing is a range management strategy that might be able to simultaneously optimize livestock production objectives and wildlife habitat objectives.

• We compared patch-burn grazing to a traditional range management strategy in multiple pastures, representing a variety of land ownership and management histories, dispersed across a relatively large geographic area. Our results likely represent what land managers could expect if they adopted patch-burn grazing in similar situations.

• We found that cattle performance in pastures managed with patch-burn grazing did not differ from that found in pastures managed with a traditional range management strategy. This suggests that land …

What Role Can Ceqa Play In Reaching Ghg Emissions Reductions Goals Set Forth In Ab 32 – An Analysis Of Ceqa, Ab 32, And Recommendations For Ceqa Reform, Eleanor Gilbert

Master's Projects and Capstones

The Global Warming Solutions Act of 2006 (AB 32) intends to reduce the effects of climate change through several mechanisms, including greenhouse gas (GHG) emissions reduction. AB 32 established a statewide GHG emissions goal, which requires California to decrease its GHG emissions to 1990 levels by 2020. The California Environmental Quality Act (CEQA) is an environmental assessment law adopted in 1970 that requires lead agencies (private developers, public agencies, etc.) to consider and disclose the potential significant environmental impacts of new development projects the lead agency is planning. CEQA has attracted much controversy since adoption and continues to be the …

Integrating Traditional Ecological Knowledge With Modern Day Ecosystem Management And Restoration Practices, Leialani O. Hufana

Master's Projects and Capstones

Traditional ecological knowledge (TEK) is a fairly new area of research that can supplement science research and modern day ecosystem management practices. Indigenous cultures and local communities have been using and passing on TEK in forestry, agricultural, and aquaculture/marine ecosystem management. Through a review of literature, TEK in Hawaiʻi was compared to TEK in other countries. TEK was also compared to modern day ecosystem management practices to determine if TEK could be integrated. In Hawaiʻi an ahupuaʻa, a land transect that cuts the islands in sections from mountain to sea, was an integrated watershed based management system. TEK in ahupuaʻa …

Deep Energy Retrofits Using The Integrative Design Process: Are They Worth The Cost, Daniel S. Bertoldi

Master's Projects and Capstones

The McKinsey Global Initiative identified existing building retrofits as an integral component to achieve a 75% reduction in greenhouse gas emissions in the United Sates by 2050 (Fluhrer, Maurer, & Deshmukh 2010). However, this will require energy efficiency retrofits for existing buildings to be deployed more frequently and achieve higher energy savings on average. Deep Energy Retrofits using the Integrative Design Process can result in 30-60%+ energy savings in office buildings. Because Deep Energy Retrofits require higher upfront capital costs, in an economy still recovering from the economic downturn, financial decision makers may not be inclined to invest more capital …

Refining Dendrochronology To Evaluate The Relationship Between Age And Diameter For Dominant Riparian Trees In The Redwood Creek Watershed, Devin Barry

Master's Projects and Capstones

Methods of dendrochronology by means of incremental coring

have been refined in this study for specific use in northern

California riparian floodplains. Little information is available

on riparian dendrochronology because of the challenges of

analyzing riparian tree species. Three dominant tree species

(Alnus rubra, Umbellularia californica, Acer macrophyllum)

in the floodplain of Redwood Creek were evaluated for the

relationship between age and diameter at breast height (DBH)

using a least squares linear regression analysis. Through this

study, complications with analysis for the riparian tree species

led to a more thorough investigation as to enhancing core

quality and annual growth ring …

An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom

School of Natural Resources: Faculty Publications

We investigated the efficiency of DK-1 and Macabee® pocket gopher (Geomys bursarius) traps placed in lateral tunnels in both open and closed tunnel sets in rangeland and nonirrigated alfalfa fields in Nebraska. We observed no statistical difference between the traps in capture efficiency when used in open, versus closed, tunnel sets. Trapping of pocket gophers was more effective in rangeland (probability of capture in a single tunnel system using 3 traps; 63%) than nonirrigated alfalfa fields (26%). We did not determine whether this variance was due to behavioral differences between Geomys bursarius and Geomys lutescens. We found that trapping pocket …

School of Natural Resources: Faculty Publications

Anthropogenic changes to land cover (LCC) remain common, but continuing land scarcity promotes the widespread intensification of land management changes (LMC) to better satisfy societal demand for food, fibre, fuel and shelter. The biophysical effects of LCC on surface climate are largely understood, particularly for the boreal and tropical zones, but fewer studies have investigated the biophysical consequences of LMC; that is, anthropogenic modification without a change in land cover type. Harmonized analysis of ground measurements and remote sensing observations of both LCC and LMC revealed that, in the temperate zone, potential surface cooling from increased albedo is typically offset …

Publications from President Jonathan G.S. Koppell

Arizona’s vulnerable populations are struggling on a daily basis but usually do so in silence, undetected by traditional radar and rankings, often unaware themselves of their high risk for being pushed or pulled into a full crisis. Ineligible for financial assistance under strict eligibility guidelines, they don’t qualify as poor because vulnerable populations are not yet in full crisis. To be clear, this report is not about the “poor,” at least not in the limited sense of the word. It is about our underemployed wage earners, our single-parent households, our deployed or returning military members, our under-educated and unskilled workforce, …

Net CO₂ exchange data of legume crops at 17 flux tower sites in North America and three sites in Europe representing 29 site-years of measurements were partitioned into gross photosynthesis and ecosystem respiration by using the nonrectangular hyperbolic lightresponse function method. The analyses produced net CO₂ exchange data and new ecosystem-scale ecophysiological parameter estimates for legume crops determined at diurnal and weekly time steps. Dynamics and annual totals of gross photosynthesis, ecosystem respiration, and net ecosystem production were calculated by gap filling with multivariate nonlinear regression. Comparison with the data from grain crops obtained with the same method …
